2.3 Checking and Controlling the Installation Site
CAUTION
D Always hold the case when carrying the Inverter.
If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.
D Attach the Inverter to a metal or other noncombustible material.
Fire can result if the Inverter is attached to a combustible material.
D Install a cooling fan or other cooling device when installing more than one Inverter in the same
enclosure so that the temperature of the air entering the Inverters is below 45 _ C.
Overheating can result in fires or other accidents.
Install the VS-626MC5 in the installation site described below and maintain optimum conditions.
2.3.1 Installation Site
Install the Inverter under the following conditions.
Type Ambient Operating Temperature Humidity
Enclosed wall-
mounted --10 to 40_C 90% RH or less (no condensation)
Open chassis --10 to 45_C 90% RH or less (no condensation)
Protection covers are attached to the top and bottom of the Inverter. Be sure to remove the protection covers
before installing a 200 or 400 V Class Inverter with an output of 15 kW or less in a panel.
D Install the Inverter in a clean location free from oil mist and dust. It can be installed in a totally enclosed
panel that is completely shielded from floating dust.
D When installing or operating the Inverter, always take special care so that metal powder, oil, water, or
other foreign matter does not get into the Inverter.
D Do not install the Inverter on combustible material, such as wood.
D Install the Inverter in a location free from radioactive materials and combustible materials.
D Install the Inverter in a location free from harmful gasses and liquids.
D Install the Inverter in a location without excessive oscillation.
D Install the Inverter in a location free from chlorides.
D Install the Inverter in a location not in direct sunlight.
2.3.2 Controlling the Ambient Temperature
To enhance the reliability of operation, the Inverter should be installed in an environment free from ex-
treme temperature increases. If the Inverter is installed in an enclosed environment, such as a box, use a
cooling fan or air conditioner to maintain the internal air temperature below 45
qC.
2.3.3 Protecting the Inverter from Foreign Matter
Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Always remove the cover from the Inverter after completing installation. Otherwise, ventilation will be
reduced, causing the Inverter to overheat.
